SPECIFICATION forming part of Letters Patent No. 359,192, dated March 8, 1887.

Application filed August 10, 1886. Serial No. 210,527. (X0 model.)

To all whom iii-may concern:

Be it known that I, JOHN B. VOGEL, a resident of New Orleans, in the parish of Orleans and State of Louisiana, have invented an Improved Decorticating-Machine, of which the following is a full, clear, and exact description, reference being made to the accompanying drawings, in which Figure l is a side elevation of my improved decorticating-machinc. Fig. 2 is a vertical crosssection of the upper part of the same. Fig. 3 is a vertical longitudinal section thereof.

This invention has for its object to produce a machine for decorlicating fiber in such manner that the fiber shall not only be crushed, but also scraped and dragged, for the purpose of obtaining the mostsatislaetory effect.

The invention consists, principally, in combining a bladed drum with an opposite recessed drum and with a revolving skeleton frame around the recessed drum, and mechanism for revolving the said skeleton frame faster than the bladed and the recessed drums, all as hereinafter more fully described.

In the frame D of the machine are the bearings of two drums or rollers, A and B, which are mounted, respectively, upon shafts (c and I). These shafts have their hearings in the frame D. The upper roller or drum, A, has series of projecting blades (Z. Eight such blades are shown in Fig. 2, but a greater or less number may be used instead.

The lower roller or drum, B, has no projecting blades, but has as many depressions c on its periphery as the roller A has blades. Around'this lower roller, I3, is drawn an indiarubber tube, E, which serves as a cushion for the opposite blades, (2, of the upper drum, A, when the same press the fibers against a depression, c, of the roller I3.

0 is what I term a skeleton frame, which has half the number of longitudinal bars that the drum A has blades. The said longitudinal bars (being marked f in Fig. 2 of the drawings) are secured at their ends to plates 9, that turn loosely on the shaft Z),'one of said plates being at its hub connected with a pinion, h, which gears into a toothed wheel, 1', that is mounted upon the shaft to, as shownin Fi 3, The number of teeth of the wheel i is double that of those 011 the wheel. 7:, so that the skeleton frame G, which consists of the parts F G, will be revolved twice as fast as the shaft (1,. The shafts a and b are geared together by toothed wheclsj and k, which are of equal diameters, so that the drums A B will be revolved with equal speed, the skeleton frame C being revolved. twice as fast as said drums; hence whenever rotary motion is imparted to the shaft 0 by belt or pulley Z, or by other means, that motion will be transmitted to the roller A, and from the shaft a to the skeleton frame C. The eight (more or less) blades d of the upper roller, A, will always press into the depressions c of the roller B; but the skeleton drum or frame 0, which moves twice around the roller B while the same turns once around its axis, bringsits hladesfso that they alternately overlap one after another of the eight blades of the drum A. The effect of this combination is that when the blades d of the roller A. strike in a depression of the roller B the blade f of the rapidly-revolving skeleton drum 0 will scrape the fiber in run ning along it, and by raising the fiber will also tend to slightly draw it back from between the grasp of the rollers A B.

m m in Fig. 2 are the feedrollers which supply the fiber to the machine, and nu are the discharge-rollers. The fcedrollers are revolved by gear-connection 0 with the shaft a,or by other suitable means.

I. elaim 1. The combination of the bladed drum A with the recessed drum I3 and mechanism for revolving them with equal speed with the skeleton frame, which embraces the drum B, and with mechanism for revolving said skeleton frame twice as fast as said drums are revolved, substantially as herein shown and de scribed.

2. The combination of the bladed drum A, recessed drum B, elastic tube E, skeleton frame C, and mechanism for revolving the drums A I3 and skeleton frame 0 in the ratio specified.

JOHN B. VOGEL.
